插件照亮 0.7 与 jQuery 1.9.1 或 jQuery-UI 1.10.3 不兼容 ->类型错误:$.css(...) 未定义

The github page of jquery still contains a matching function (see line 111):

jQuery.fn.extend({
  css: function( name, value ) { ....

我的问题

• 在 jQuery.js 或 jQuery-ui 中是否发生了任何可能导致 $.css(...) 失败的重大更改
• 如何使插件与最新(或至少 1.9.1)版本的 jquery 和 jquery-ui (1.10.3) 兼容

用户 Dave 询问我如何加载 javascript 库.我按以下顺序同步加载它们:

User Dave asked how i load the javascript libraries. I load them synchronously in the following order:

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script src="jquery.illuminate.0.7.js"></script>

用户 Sumurai 指出 这可能与已弃用的 curCSS 有关/a>.我在 jQuery 1.9.1 中找到了以下代码:

User Sumurai pointed out that it could have to do with the deprecated curCSS. I found the following code in jQuery 1.9.1:

jQuery.extend({
// Add in style property hooks for overriding the default
// behavior of getting and setting a style property
cssHooks: {
   opacity: {
         get: function( elem, computed ) {
        if ( computed ) {
        // We should always get a number back from opacity
        var ret = curCSS( elem, "opacity" );
        return ret === "" ? "1" : ret;
        }//if
     }//get
   }//opacity
},//cssHooks
    // more properties for jQuery.extend ....

所以 jQuery 1.9.1 仍然使用 curCSS 作为 cssHooks.opacity.该插件为 cssHooks 添加了另一个属性:$.cssHooks.boxShadowBlur.但据我所知，此方法与 cssHooks.opacity 无关.因此 curCSS 应该没有效果.

So jQuery 1.9.1 still uses curCSS for the cssHooks.opacity. The plugin illuminate adds another property to cssHooks: $.cssHooks.boxShadowBlur. But as far as i can tell this method has nothing to do with cssHooks.opacity. Therefore the curCSS should have no effect.

推荐答案

哇，这需要一些调试.

问题在于，Illumination 假设 jQuery 不支持 box-shadow 属性，但较新的 jQuery 版本支持.这意味着当供应商前缀不可用(它们不在最新的 FireFox 中)时，您将获得无限循环或未定义的属性.幸运的是，Illumination 使用了一个未定义的属性 BoxShadow 而不是使用 boxShadow 产生的无限循环(正如我发现的那样，这会导致几个浏览器挂起).

The problem is that illuminate assumes that jQuery doesn't support the box-shadow property, but the newer jQuery version does. That means that when vendor prefixes aren't available (which they aren't in the latest FireFox), you get either an infinite loop or an undefined property. Fortunately illuminate went with an undefined property BoxShadow instead of the infinite loop which would have come from using boxShadow (as I found out, leading to several browser hangs).

这就是问题所在，解决方法是什么?从照明中删除有问题的代码.support.boxShadow 的所有情况都应更改为简单的 'boxShadow'，并删除 cssHooks.boxShadow 块.您还可以删除首先设置 support.boxShadow 的位.

So that's the problem, what's the fix? Strip the offending code from illuminate. All cases of support.boxShadow should be changed to simply 'boxShadow', and the cssHooks.boxShadow block removed. You can also delete the bit which sets support.boxShadow in the first place.

我的测试用例在这里:http://jsfiddle.net/JbTcs/2/ 和在 FireFox 和 Chrome 中工作，我被告知 IE10.光照的固定源代码为:

My test case is here: http://jsfiddle.net/JbTcs/2/ and works in FireFox and Chrome, and I'm told IE10. The fixed source code for illuminate is:
